SPECIIEIUATION forming part of Letters Patent No. 720,975, datedFebruary 1'7, 1903. Application filed November 25, 1901. fierial No.83,669. (lilo model.)

To all whom 1 itm-cty concern:

Be it known that I, LABS G. SGHULT, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,

5 have invented certain new and useful Improvements in Transfer-Files,of which the following is a specification.

The object of this invention is to produce a transfer-file embodying thenovel features hereinafter more fully shown and described.

In the accompanying drawings, Figure l is a perspective view ofatransfer-file separated for the removal of some of its leaves. Fig. 2is a longitudinal section showing the binder r5 mechanism. Fig. 3 is atransverse section showing the locking mechanism for the filecover. Fig.4 is a top plan view of the binder mechanism, showing the means for,securing the top member thereof in position.

Like letters of reference indicate corresponding parts throughout theseveral views,

prongs of the opposite side bar of the binder,

to be next described.

O is the opposite side bar of the binder device, having the prongs Ofixed thereto, as by riveting. plate 0 pivoted by the stud C upon itsouter face andlying in close contact there- 0 with. At one end the plate0 carries the stud O fixed to said plate, and at its opposite end has anelongated opening'C' through which the stud C secured rigidly to theside bar 0, projects. A straight spring 0 extends from the stud 0 aroundthe pivotal stud G its outer end lying in contact with the stud C.Openings C for the reception of the prongs B extending through the sidebar 0 and through the pivotal plate C at opposite sides of the center ofthe former, are

This bar is provided with arespectively coincident in the side bar 0 andthe pivotal plate C when said plate is moved against the action of itsspring 0 When the prongs B are placed in the openings C and the ends ofthe prongs G in the openings B in the side bar B, the spring-plate C ispushed aside against the action of the spring 0 and the prongs 13 entertheir openings in the side bar 0. As soon as said prongs project throughsaid plate the pivbe otal plate 0 by reason of its spring action engagesthe notches B in the upper ends of the prongs B.

A keeper D, somewhat of L shape, and therefore having the arms D and Dis se- 6: cured, with the arm D in contact with the flexible connectionA between the covers A and A. The other arm D of this keeper is providedwith an opening D and the position of the keeper is such with relationto the holder mechanism that the opening D is adapted to engage with theupper end of the stud G upon which the pivotal plate 0 turns. 7 When thefile is closed, the keeper is in engagement with said stud and holds thefile firmly together. When it is desirable to open the file, the keeperD is raised from engagement with the stud G by the thumb of the operatorand the cover A laid back from the holder mechanism. The spring-plate isSo then turned upon its pivotal stud C and the side bar 0 removed. Thisleaves the binder in the position illustrated in Fig. 1, in whichposition the make-up of its contents may be changed. When thearrangement is complots, the sidebar 0 is put in place, the back A?brought up into its proper position, and the keeper D snapped over thetop of the pivotal stud C It is clear that many slight changes may bemade in the construction of this file without departing from the spiritand scope of my invention. Henceldesiretohaveitunderstood that I do notlimit myself to the precise details of the embodiment herein shown andde- 5 scribed.

I claim as my invention- 1. In a file, in combination, a hinged cover; abinder device comprising a side fixed to said cover, and a removableside, each of said IOU sides being provided with holding-prongs; and akeeper secured to said cover, adapted to engage with said removableside.

2. In a file, in combination, a hinged cover; a binder device comprisinga side fixed to said cover and provided with prongs, a removable sidealso provided With prongs, said removable side having openings thereinfor receiving the ends of the prongs of said fixed side, and means onsaid removable side for holding said side in releasable engagement withthe prongs of said fixed side; and a keeper secured to said cover,adapted to engage with a portion of said binder device.

3. In a file, in combination, a hinged cover; a binder device comprisinga side fixed to said cover and provided with prongs having notchesintheir outer ends, a removable side also provided with prongs, saidremovable side having openings therein for receiving the outer ends ofthe prongs of said fixed side, and a pivoted plate on said removableside, adapted to engage the notched ends of the prongs of said fixedside, to hold said removable side in releasable engagement with theprongs of said fixed side; and a keeper secured to said cover, adaptedto engage with a portion of said binder device.

4. In a file, in combination, a hinged cover;

a binder device comprising a side fixed to said cover and provided withprongs having notches in their outer ends, a removable side alsoprovided with prongs, said removable side having openings therein forreceiving the outer ends of the prongs of said fixed side, a pivotedplate on said removable side, and a spring adapted to hold said pivotedplate in releasable engagement with the notched ends of the prongs ofsaid fixed bar; and a keeper secu red to said cover, adapted to engagewith a portion of said binder device.

5. In a binder, in combination, a side bar provided with prongs; asecond side bar having openings therein for'receiving the ends of theprongs of said first-mentioned bar, said second side bar also beingprovided with prongs; and means on said second side bar for holding saidbar in releasable engagement with the prongs of said first-mentionedside bar.

6. In a binder, in combination, a side bar provided with prongs havingnotches in their outer ends; a second side bar having openings thereinfor receiving the outer ends of the prongs of said first-mentioned bar,said side bar also being provided with prongs; and a pivoted plate onsaid second bar adapted to engage the notched ends of the prongs of saidfirst-mentioned bar, to hold said second bar in releasable engagementwith said prongs.

7. In a binder, in combination, a side bar provided with prongs havingnotches in their outer ends; a second side bar having openings thereinfor receiving the outer ends of the prongs of said first-mentioned bar,said side bar also being provided with prongs; a pivoted plate on saidsecond bar; and a spring adapted to'hold said pivot-ed plate in releasable engagement with the notched ends of the prongs of saidfirst-mentioned bar.
